The Short Mayo Composite is the name given to a piggyback long-range seaplane/flying boat combination produced by Short Brothers to provide a reliable long-range air transport service to the United States and the far reaches of the British Empire and the Commonwealth.

The Yankee Clipper flew across the Atlantic on a route from New York to Southampton. The inaugural trip occurred on June 24, 1939. The Yankee Clipper crashed February 22, 1943 in Lisbon, Portugal. During the war the Yankee was assigned to the navy and allowed to continue passenger service between the United States and Portugal (indirectly serving all Europeans able to reach Lisbon). On February 22, 1943, after completing its 241st transatlantic flight, the Yankee Clipper circled for a landing on the Tagus River in Lisbon, Portugal. Her port wing tip skimmed the water, dug in, and she slammed into the river, breaking into several pieces, and sank inside of 10 minutes.

The Martin P6M SeaMaster, built by the Glenn L. Martin Company, was a 1950s strategic bomber flying boat for the United States Navy that almost entered service; production aircraft had been built and Navy crews were undergoing operational conversion, with a service entry about six months off, when the program was cancelled on August 21, 1959. Envisioned as a way to give the Navy a strategic nuclear force, the SeaMaster was eclipsed by the Polaris submarine launched ballistic missile. Due to the political situation at the Pentagon, the Navy promoted the P6M primarily as a high speed minelayer.

The An-2 Colt has been used as a paratroop transport, glider tug, navigation trainer, utility transport and light bomber. Despite being a versatile and adaptable machine, the large, fabric-covered An-2 biplane remains firmly rooted in much earlier days of aviation.
The An-2 prototype was first flown on August 31, 1947, and the aircraft is still in production, although the Antonov Bureau has not produced any since 1960. The An-2s designer, Oleg Antonov, had been an aircraft designer during the Second World War. He then formed his own bureau with the intention of creating an aircraft capable of almost any task. He succeeded. Originally designed for the Ministry of Agriculture and Forestry in the former Soviet Union, the aircraft was soon adopted by the Soviet Air Force and built for its client states. It is ideally suited to less developed countries because it requires little maintenance and is easy to fly.
The An-2's admittedly-antiquated design gives it extremely short take-off and landing (STOL) capabilities. This is partly achieved not only by the high-lift double wings, but by the use of the drooping ailerons which can be lowered 20 degrees to compliment the flaps. The wings are covered in fabric aft of the front spar and the tailplane is also covered with fabric, making field repairs easy. It has a crew of two in a heated crew compartment and a single bay running the length of the aircraft.
The An-2 is still in service with over 30 air forces and has been used by Aeroflot and other eastern airlines. With the collapse of the communist regime over a decade ago, a small number of An-2s have begun to appear on the civilian rosters in Europe and the United States, although the type is difficult to register in the United States due to regulatory issues

Gabon Express was an airline based in Libreville, Gabon. It operated scheduled passenger services and passenger and cargo charters. It ceased operations in June 2004.
The Sud Aviation SE 210 Caravelle was the first short/medium-range jet airliner produced by the French Sud Aviation firm starting in 1955 (when it was still known as SNCASE). The Caravelle would go on to be one of the more successful European first generation jetliners, selling throughout Europe and even penetrating the United States market, with an order for 20 from United Airlines. The Caravelle established the aft-mounted-engine, clean-wing design that has since been used on a wide variety of subsequent aircraft. Filmed by Just Planes DVDs.

From Wikipedia, the free encyclopedia: On 25 August 1950, Convair issued a formal proposal for a swept-winged version of the B-36 with all-jet propulsion. The United States Air Force was sufficiently interested that on 15 March 1951, the USAF authorized Convair to convert two B-36Fs (49-2676 and 49-2684) as B-36Gs. Since the aircraft was so radically different from the existing B-36, the designation was soon changed to YB-60.
